| threeD | Use this to specify whether the clip should be a 2D or 3D clip. The threeD parameter defaults to true. |

AudioClip 返回的 AudioClip。
返回从下载的数据生成的 AudioClip（只读）。
The data must be an audio clip in Ogg(Web/Standalones), MP3(phones) or WAV. Note that the XM, IT, MOD or S3M format can also be streamed in, but realtime playback of these is not supported, because all the data must be present before playback can begin, so for these tracker formats AudioClip.isReadyToPlay must return true before the clip may be assigned to an AudioSource and played back.
